Yes, and 30,000 years ago was the height of the Eredar civilization that Sargeras visited. We don't know exactly when either race truly began their civilization, but since the Legion came to the Eredar 14,000 years before the Zandalari found the Aqir, it stands to reason that their civilization is still much older. It also scans as the Eredar/Draenei are also far longer-living than the Trolls, with some of the Draenei living on Azeroth today remembering Argus before the Legion came.
